Better TTS default engines. Flite is Flite, but what about defaulting to Pico TTS? I know there is a forum post on it, but the Polly integration is amazing and super cost-effective compared to the old-guard solutions from Nuance, Cepstral, etc. It would be nice if there was a module that made it easy to add the Amazon, Microsoft, IBM, Google TTS offerings.
Also in the same regard ASR. This would add tremendous utility to our offerings.
